SIGNALING DEVICE.

Appiicanon nea January e, 192i.l serial no. 435,392.

To ZZ wlw/n, t may concern.'

Be it known that l, ERNEST LnoNARD lVAnLn-r, of Brighton, England, a subject of the King of Englanchhave invented certain new and useful improvements in SignalingI Devices, of which the following is v a specification.

rIhis invention relates to a. new or improved visual, and if desired, audible indicator for signaling purposes, more particularly for use in connection with self-propelled vehicles, although the device is capable of use in any other capacity where signaling is required as on ships, railways, etc.

An object of the invention is to provide a simple cheaply constructed and efficient indicator 0f the semaphore type whereby both visual and if desired audible signals may be given. An indicator according to this invention comprises an arm having one or more transparent surfaces and a lamp therein with means for rotating said arm through a pre-determined number of degrecs, whereby upon the movement of the arm the light rays will pass through a visual indicating medium, or also through the audible medium, if present, or through both simultaneously.

Another object of the invention is to provide a sgecial construction of semaphore signaling arm iny the form of an arrow adapted to revolve about its centre.

ln order that the invention may be clearly understoodn practical applications of the in vention will now be described by aid of th accompanying drawings in which Fig. l is a sectional elevation of a complete signaling device embodying the invention. Fig. 2 is a front view thereof.

Referring to the drawings, the indicator therein shown is formed 0f a frame 29 preferably shaped like an arrow and having translucent or transparent fillings 30 and tapering chambers 3l behind said fillings acting as reflectors whereby the rays from a centrally placed electric lamp 32 may, at certain times, be reflected to illuminate said suing.

At the centre of the indicator is a sleeve 34 surrounding a fixed sleeve 35 carrying the lamp 32 and co-operating mechanism. These sleeves are provided with perforations 86 and 37 respectively whereby in certain positions of the indicator angularly about the xed sleeve the rays of the lamp inay pass, whereas in other positions such rays are obscured. Lenses or coloured glasses may be arranged in` some-of 'said perforations. f

The arrangement is preferably such that when the indicator is upright and pointing downwards meaning for example straight on, its transparent fillings 30 are not illuminated; when turned from suchposition through about 45 degrees, the ltransparent filling will become illuminated, ,and in such position also a switch may make contact to an audible warning signal not shown.` On passing this warning position the audible signal may cease, but the indicator will remain illuminated. rIhe operator may, however, arrest the indicator at the completion of 90, 180 or 270 degrees of revolution, thus indicating respectively an intended turn to the right, stop and turn to the left. At the stop position the indicator will preferaily be illuminated through a' red lens or g ass.

This device may be combined with means for showing a red light as usually shown by back lamps of motor cars. For this purpose the fixed sleeve aforesaid is shown as capped at the end by a red lens or glass 33.

In order that the device may also serve for illuminating a permanent indicator such as a number plate, there may be fitted an annular window 38 'preferably rearward of and forming part of thel indicator sleeve through which the light rays may pass in all positions of the indicator but to confine such rays to the direction required the inner fixed sleeve may carry a suitable mask 39 provided with an opening or openings only where the light is to issue.

The rotatable sleeve 84 is revolubly mounted on an extension 35a of the fixed sleeve and under the action of a. spring 40 which tends to return it to normal position, after release of the operating means. The rear end of the device is also shown as enclosed in a casing 4l closed by a cap 42 openings Vilhat I `claim as my invention and desire to secure by Letters Patent of the United States is l. In an'indieator for the purpose specified, a supporting sleeve having a chamber in its outer end and openings at predetermined spaced points in its sides; a light in said Chamber; a second sleeve rotatably mounted on the first sleeve, and surrounding the said chamber, said second sleeve having adapted to register with the openings 1n the first sleeve at predetermined rotatably displaced positions of the second sleeve upon the first sleeve; an arm connected to said rotatable sleeve and projectingrr on diametrieally opposite sides thereof, said arm having a ehamber at each side of the sleeve each chamber having" a transparent closure in its Yfront side, said chambers *being illuminated only when the openings in the rotatable sleeve register with the proper openings in the first sleeve; and means for holding the rotatable sleeve and arm normally in sueh position that the chambers are not illuminated; and means for rotatably displacing the arm `and movable sleeve on the fixed sleeve to certain predetermined positions wherein the openings in the sleeves register so that the chambers in the arm are illuminated.

2. In an indicator as set forth in claim l, the rotatable sleeve having a Window opening exterior `to ,thearin7 and the inner sleeve having an opening* whereby light may pass to and through said Window.

3. In an indicator as set Jforth in claim l, a casing` sup-porting the first sleeve, and a. spring in said easing,` t'or returning' the rotatable sleeve and arm to normal position `on the first sleeve.
